Application filed April 8, 1911. Serial No. 619,777.

T 0 all whom it may concern:

Be it known that I, LEWIS A. BAKER, a citizen of the United States, and a resident of Elgin, in the county ofKane and State of .Illinois, have invented certain new and useful Improvements in Machines for Filling Receptacles with Liquid; and I" do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in filling machines of that class in which cans or like receptacles are filled from a common or central liquid tank, the arrangement being such that a'plurality of cans are simultaneously filled, and are successively delivered to and discharged from the machine, the filling of the cans or receptacles and their discharge from the machine being automatically effected after the cans or like receptacles are delivered to the machine. The machine is of the general type shown in my prior United States Letters Patent, Number 910,265, dated January 19th, 1909.

Among the objects of the invention is to provide an improved adjustable measuring device by which. the contents fed to the receptacles may be accurately measured and maintained by a displacing element arranged to be adjusted to the charge meas uring chamber. v

A further object of the invention is to provide an improved automatically operated valve mechanism for controlling the delivery of the measured charges to the re- 'ceptacles placed to receive said charges.

A further object of the invention is to provide a simple and improved feeding means for feeding the cans or receptacles to the rotating carrier or platform which supports the receptacles while they are being filled and fordischarging the filled cans therefrom.

Other objects of the invention are to improve and simplify filling machines of this general class and the invention consists in thematters hereinafter set forth and more particularly pointed out in the appended claims. I

In the drawings,Figure 1 is a vertical sectional view of a filling machine made in accordance with my invention. Fig. 2 is a plan view thereof. Fig.. 3 is a horizontal section'on the indirect line 33 of Fig. 1. Figs. 4 and 5 are detail sections showing the measuring chambers, valve mechanism therefor and the displacing elements for varying the charge delivered from said chambers, together with the means for supporting the cans and presenting the cans to the measurmg chambers. Figs. 6 and 7 are horizontal detail sections illustrating the valve parts for the measuring'chambers and the means for controlling said parts.

The base 10 of the machine has a central raised portion 11 in which is fixed the lower end of a post or standard 12. A sleeve 14 surrounds and rotates on said standard and to the lower end of the sleeve 14 is fixed a large beveled gear wheel 15 which meshes with a pinion 16 of a driving shaft 17 that it mounted in a bearing 18 of said base and a standard 19 and is provided with light and loose pulleys 20, 21. Said sleeve carries at its upper end to rotate therewith a reservoir consisting of a bottom plate 24 and a sheet metal ,surrounding wall 24. The hub 25 of the bottomplate is loosely mounted on t-he sleeve 14. The reservoir may be raised and lowered to adapt the machine to cans of different heights by means of a sleeve 26 screw-threaded to the sleeve 14 and supporting the reservoir, through roller bearings interposed between said hub and sleeve. The said sleeve 26 is formed with a beveled gear wheel 27 that meshes with a pinion 28 carried by an adjusting shaft 29 that is mounted in a hearing 30 depending from the bot-tom of the reservoir and having a hand wheel 31, whereby the sleeve 26 may be raised and lowered to raise and lower the reservoir.

' 32 designates an annular, horizontal plat: form or carrier arranged beneath the reservoir and keyed or otherwise non-rotatively fixed to the sleeve 14 to rotate therewith and with the I'ESBI'VOII'. The platform 32 is provided-near its periphery and above the same with angularly separated gage plates 33 upon which the cans A .to be filled are directly delivered and from which the filled cans are discharged. They have flaring marginal rims which guide andhold the.

ings 35, that depend from and are attachedto the carrier. Said lift rods are provided at their lower ends with bearing wheels or rollers 37 which rest and roll on a cam ring 38 that is supported on brackets 39 fixed to the upright portion 11 of the base 10. The platform is provided at its marginal portion with radial openings 40 over which the gage plates are supported, and the gage plates are'provided at their'inner ends or hubs with lugs 41 which engage the inner ends of the openings 40 to hold the gage plates in their proper radial positions during the rising and falling movements thereof:

Arranged above and in alinement with the gage plates are a plurality of charge measuring chambers 45 consisting of hollow cylinders which are open at their upper ends and -which extend .through openings in and are supported on the bottom of the supply reservoir. Said measuring chambers are closed at their lower ends by end walls &6 which terminate in filling nipples 47 that. are adapted to register with the openings 1) in the cans or receptacles B. Automatically operated valves 48 cooperate with said nipples 47 to control the discharge of the material from said chambers to the cans below, as will hereinafter more fully appear. The chambers are shown as provided between their ends with exterior,

cross section to said chambers.

conical or beveled annular flanges 49 which fit conical,,upwardly facing seats in said v bottom wall surrounding the openings through which the chambers extend, and are clamped in place by the lock nuts50,which are screw-threaded to the-chambers below, and bear upwardly against the lower side of said reservoir bottom wall. In this manner a fluid tight joint is provided, the integrity of which may be insured by the interposition of a suitable packing between the tapered parts if desired.

Supported within the upper open ends of the charge measuring chambers are displacing elements 52 which fit closely within said chambers and extend a distance above the same, and are adapted to be adjusted vertically therein. Said displacing elements, as herein shown, take the form of cylinders to conform to the illustrated cross section of the charge measuring chambers, and will. in any event closely fit and correspond in displacing elements are supported in the charge measuring chambers b means permitting .vertlcal adjustment 0 the displac- The said and constitute valves to shut 0 ing elements in said chambers whereby t0 filled, and are further formed with parts that cooperate to constitute valves by which the flow of material from the reservoir to the charge measuring chambers is controlled. As herein shown these results are eflected by the following construction Surrounding the upper ends of the charge measuring chambers are split clamping rings 53 which are annularly grooved at their lower sides to fit over or interlock with radial flanges 54 surrounding the open upper ends of said chambers. Said rings have cylindric flanged portions 55 which closely embrace the displacing cylinders 52, and are provided at their ends with lugs 56 (Fig. 1) through which extend clamping bolts 57. By loosening the clamping rings the displacing cylinders may be moved upwardly or downwardly to the proper point 'to adjust the charge measuring space in the chambers 45, below the cylinders, to receive a predetermined charge of material for filling a certain size of can, and when the clamping rings are tightened the displacing cylinders are locked from vertical movement therein. The displacing cylinders may be provided with graduation marks 58 to be read from thetops ot the clamping rings by which to adjust the cylinders. In order that the displacing cylinders may be removed from the charge measuring cham bers without releasing the clamping bolts 57, the lower lips 59 of the clamping rings are notched, as shown at 60 (Figs. 6 and 7) to pass over the flanged lugs 54 at the upper ,ends of the chambers (see dotted lines in Figs. 6 and 7). The parts are locked together by turning the clamping rings to bring the notches out of line with the flanged lugs, as indicated in said Figs. 6

to the bottoms of the cylinders. When the cylinder ports are opposite the chamber ports, as shown in Figs. 5 and 7, the material is free to flow from the reservolr into the charge measuring chambers to fill the latter, but when the cylinders are turned to bring their elongated. ports 66 angularly out of line with the chamber ports 65 the walls of the displacing cylinders close said chamber ports, as shown in Fi s. 4; and 6, the flow of material to said charge measuring chambers. Means hereinafter described are 'provided for turning the cylinders in :proper timed relation relatively to the other operations of the machine for .alternately opening and closing the valves thus constructed and arranged. The cylinder ports are made considerably longer than the chamber ports 65 in order to adapt the longer ports to all vertical adjustments of said cylinder. Preferably, and asherein shown, the displacing cylinders or elements are made hollow, being made ofsheet metal with top and bottom ends walls, and the elongated ports 66 thereof are formed in suitable concave insets, as best shown in Figs. 5, 6 and 7.

The measured charges of material are discharged from the chambers through the filling nozzles 47 into cans or bottles below when the valves 48 are opened. Said valves 4-8 are provided with stems 69 that extend upwardly throughtubular guides 70 in the hollow displacing cylinders and above the cylinders and are adapted at their upper ends for connection with valve actuating means.

Referring now to the means for operating the inlet and outlet valve mechanism for the charge measuring chambers, it will be observed that the charge measuring chambers are spaced angularly around the reservoir and travel in a circular path in the rotation of the latter, and that the can gages 33 are likewise disposed on the platform or carrier 32 and travel therewith to hold the cans vertically beneath the filling nozzles 47 of said charge measuring chambers. The clamping or locking rings 53 are provided at the inner sides of the chambers 45 with short arms 74, .75, the latter arms being provided at the upper sides oftheir inner ends with upstanding roller bearing.

studs 76 and the former arms being provided at the lower sides of their inner ends with downwardly extending studs 77. The upstanding roller bearing studs are adapted to strike, once during each cycle of their revoluble movement, a fixed tripping cam 78 (Figs. 1 and 2) carried by an arm 79, the hub 80 of which is non-rotatively fixed to the upper end 'of the standard 12. The downwardly extending studs 77 of the arms 74 are adapted, in a like manner, to strike the outer end of a tripping arm 81 carried by a member 82 which is shown as made integral with said hub 80. The said fixed tripping cam and arm are angularly spaced at substantially 120 degrees apart, as herein shown, and the parts are so arranged that when the tripping cam 78 acts upon the roller bearing studs of the arms 75 of the clamping rings 58 and the displacing cylinders are turned to bring the ports. and 66 out of register, as shown in Fig. 6, so as to close the charge measuring chamber inlet valves. When the studs 77 strike the trip- .ping arm 81,-said displacing cylinders are" tu'rned or rotated to bring the ports 65 and 66 1nto register and thus open the reservoir to the charge measuring chambers. It will thus-be seen that, in the arrangement shown, the inlet valves of the charge measuring chambers, comprising the ports 65 and 66, remain open throughout substantially onethird of the rotative travel of the chambers,- and will remain closed throughout the remaining two-thirds of the" travel. During substantially all the time when the inlet valves are closed the outlet valves are opened to permit the material to flow from the charge measuring chambers to the cans beneath.

The mechanism herein shown for controlling the outlet valves is made as follows :The cam ring 38 is formed wit-h a low portion a and a high portion a. The low portion a of the cam ring 38 is made slightly longer than the angular distance between the tripping arm 81 and the tripping cam 78 and is connected to the high portion of the cam ring by the cam port-ions a a the former of which is shown in Figs. 1 and 5 and both of which are indicated in dotted lines in Fig.8; the cam portion a being the ascending portion, and the cam portion at beingthe descending portion of x the cam ring.

The mechanism for opening and closing the outlet valves to discharge the material from the charge measuring chambers to the cans is so arranged that said outlet valves are closed during the time the rollers 37 of the lifting bars 34 are traveling on the low portion a of the cam ring, during which time the inlet valves to the charge measuring chambers are open, having been opened by the arm 81; and said outlet valves are open just after the inlet valves have been closed through the action of the tripping cam 78. The unfilled cans are delivered to they machine at the time the outlet valves are closed and while the charge measuring chambers are being filled, and thefilled cans are discharged from the machine just after the outlet gal inlet valves to the charge measuring chambers have been opened.

The means for opening the outlet valves, under'the control of the cam ring 38, are made as follows :85, 85 designate, vertically movable lift bars, one for each charge measuring chamber, arranged outside of the reservoir and guided in suitable guides 86. 87 attached to the wall 24: of said reservoir. To the upper ends of the lift bars are attached brackets 88 which carry inwardly directed arms 89 that engage under suitably shaped heads 91 fixed to the upper ends of the stems 69 of the discharge valves 48. Said arms 89 are pivoted to the brackets 88 at 92 so that the arms may be swung upves have been closed and the.

' wardly and outwardly over the brackets to permit the displacing cylinders 52 to be raised out of the charge measuring chambers for the purpose of cleaning the latter.

Fixedly attached to the lower ends of the lift bars 85 are forked members 93, one arranged beloweach charge measuring chamber, and arranged when in their lowermost position a distance above the-gage plates 33 slightly greater than the height of the cans or other receptacles to be filled, so that the cansmaybe freely delivered thereunder by the can delivering mechanism hereinafter described. The forked members 93 are attached to'the lift bars by set screws 94 to permit them to be adjusted vertically, within a limited range, to adjust the machine to cans of different heights.

The cans are delivered upon the gage plates when the rollers 37 of the lifting rods 34 are riding on the low portion a of the cam ring 38 and when, therefore, the gage plates are in their lowermost positions. As

the platform or carrier 32 revolves with a can on one of the gage plates, when the latter is in its lowermost position, the roller 37 of the lifting rod 34 of said gage plate strikes the rising portion a of the cam ring just I after the inlet valve of the charge measuring chamber associated therewith has been closed through the action of the tripping cam 78. As each roller 37 rides up the rising portion a of the camring to thehigh portion a it lifts the associated can to bring the opening thereof to thenozzle 47 of the charge meas-..

uring chamber, and at the same time acts, through the forked member 93 and lifting a bar 85 to raise the outlet valve 48 to permit the material to flow from the charge measuring chamber to the can. The said outlet valve is held in its open position, as indicated in Fig. 4, until theroller 37 vofthe lifting rod 34 strikes the descending portion a? of the cam. ring 38, whereupon the outlet valve is closed.' The outlet valve is thus V closed just before the trip arm 81 acts upon the stud 77 to rotate the displacing cylinder chine between the inlet valve opening arm 81 and the inlet valveclosing cam 78, which as herein shown includes about one-third of the travel of the charge measuring chamhers, is utilized to discharge the filled cans from the machine and to deliver the empty cans to the machine. The mechanism for delivering the cans to the machine and dis:

wheels 98, 99 rotatively mounted on suitable bearing studs 100, 101 carried by said table and the inner end of a plate 102,respec tivelyi the latter arranged radial to the standar 12, with its inner end and the sprocket wheel 99 over the carrier 32. Said sprocket chain is provided at suitably spaced intervalswith outwardly directed arms 104 which engage the empty cans to carry them inwardly over the table to the gage plates 33 at the receiving side of the machine, and to carry the filled cans away from the gage plates at the discharge side of the machine. The empty cans are shown as delivered into the path of the arms 104 at the receiving side of the machine by a notched disk 106 rotative'ly mounted over the table on a stud 107, the cans being placed in the notches of the disk, either manually or automatically as desired, and being held therein and guided into the path of the chain arms by the guard bar 108; The speed of the can feed chain is so timed with respect to the speed of the carrier that as each empty can is delivered to the carrierby an arm 104 one of the gage plates 33 is in" position to receive the can.- The relation of the parts are also such that the can feed chain arms 104 engagethe filled cans as they are discharged from the rotative carrier and directs them to a take off belt 109 by which thefilled cans. are directed from the machine to any suitable --pin 112 working in a slot therein and said cam being pressed inwardly by a spring 113.

The said notched disk 106 is driven by a train of gears 114, 115, 116 indicated in dotted lines in Fig. 3. The gear wheel 114 is fixed to a shaft 117 on the lower end of which, below-the table, is mounted a star. wheel 118, the notches of which are adapted to engage the bearings 35 for the lift rods 34, whereby said tooth wheel 118 and the gears connected therewith are rotated. The can feed chain 97 is also driven from the train of gears described through the medium of a ear wheel 120' which meshes with the b gear wheel and with a'pinion 1.21 mounted on the lower end of the shaft 100 on which the sprocket 98 is mounted. The filled cans are removed from the gage plates of the carrier by means of the curved stripper bar 125 which, as herein showh,'is

fixed to the arm or plate 102 which carries the can delivering chain sprocket wheels. Said stripper bar is arranged above the level of the chain 97 and arms 104 and extends inwardly at its inner end over the gage plates to a point beyond the receptacles supported thereon. When the receptacles are brought against the outer curved edge of the stripper bar, during the rotation of the carrier, they are started olfthe gage plates toward the table 95, whereby said filled cans are in motion when they are engaged by the arms 104. Thus the cans are gently moved by said arms, and without objectionable shock toward and onto the take ofl belt 109. The filled cans are guided onto the belt between the stripper bar and a short guide bar 127 arranged at one side thereof, as shown in Figs. 2 and 3. The take ofi belt is trained about a pulley 128, shown in dotted lines in said Figs. 3 and 4, the shaft 129 of which is driven by a sprocket belt 130 that is trained over a sprocket wheel 1310f said shaft 129 and a sprocket wheel 132 fixed to a short shaft 133, the inner end of which latter carries a beveled pinion 134 that meshes with the beveled gear wheel 15, as shown in dotted lines in Fig. 3.

Themachine herein described may be used for filling cans with any fluid-like material, such as fruit extracts, syrups, jellies, milk and the like, and is especially adaptable for filling cans with relatively heavy and slow flowing liquids or syrups, because of the time given for the liquid to be discharged into the cans after the charge measuring receptacle has been filledand the inlet valves thereof closed.

The operation of the machine will be clear from the "foregoing, but may be briefly recapitulated as follows :-The empty cans are placed in the notches of the notched disk 106, either by hand or automatically, and are carried thereby into the path of the arms 104 of the feed chain, by which they are delivered to the gage plates. At the time the cans are delivered to the gage plates the outletvalves of the charge measuring chambers immediately over said cans are closed, and the inlet valves of said lattermeasuring chambers are open. In the continued rotatlon of the carrier 32 the bearing rollers 37 of the lifting rods 34 rideup on the inclined cam surface a of the cam ring 38 and lift the cans up to the discharge nozzles of said chambers and also open the outlet valves 48,; and said outlet valves remain open until the bearing rollers of the lifting rods 34 roll down on the descending portion a of the cam ring, at which time the outlet valves are closed. Before the outlet valves are opened the tripping cam 78 strikes the roller bearing studs of the arms 78 of the displacing elements or cylinders and rotate the displacing elements to close the inlet valves of the -ment to control the inlet of material to the charge measuring chambers so that only the amount of liquid delivered to the charge measuring chambers is delivered to the cans. Said inlet valves remain closed until after all of the material from the charge measuring chambers has been discharged into the cans and the discharge valves are closed.

The inlet valves are opened by contact of the tripping arm 81 with the studs 77 of the arm 74. of the rotative displacing element and the measuring chambers are filled at the timethe filled cans are being discharged from themachine and empty cans are being delivered thereto.
